Zusammenfassung:	An injection molding die is an injection molding die for molding a resin hollow body including a straight tubular portion having an inner peripheral surface that does not have a tapered portion for die removal. The injection molding die includes a core having a cylindrical portion configured to form the inner peripheral surface of the straight tubular portion. The core has a groove recessed inwardly in the radial direction and formed over a whole circumference of the cylindrical portion in an end portion of the core on a first side in the axial direction, the end portion corresponding to a rear end portion of the resin hollow body in the die-removal direction.
